General Discussion

Basic Information:

Printer Model: ender 3
MCU / Printerboard: 4.2.7

i can connect and print on this machine with my orange pi so i know it works the cord works to i stole the one i’m using to print with right now.

i have 5 machines and only 2 pi so i decided to grab an old desktop and put untubu on it. i used kiauh to install i cannot get any of the machines to connect. they show up when i use dmesg but not when i use ls /dev/serial/by-id/*,

i’m pretty new to linux and i’ve gone as far as i can go.

Copy and paste the output of sudo dmesg directly after connecting the board to your PC using the Preformatted Text option here

brltty issue is now gone but im still not getting connection. i still can connect and print with this board with an orange pi so i know it is flashed and the usb is good.

Unplug and replug the board. Then post the entire dmesg output on e.g. pastebin.
Generally copy and paste this stuff and do not use screenshots. Use the “Preformatted Text” option if you paste such stuff here

You need to include the full path for the serial device.

[mcu]
serial = usb-1a86_USB_Serial-if00-port0

This should be:

[mcu]
serial = /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

that worked thank you!
